RAILWAY TRACK CONSTRUCTION Filed Sept. 17, 19 29 4 Sheets-Sheet 4 Patented Oct. 14, 1930 FRITZ HEINEMANN, F HAMBURG, GERMANY RAILWAY-TRACK CONSTRUCTION Application filed September 17, 1829, Serial No. 393,284, and in Germany September 25, 1928.

-This invention relates to a railway track construction with unplerced 1ron transverse sleepers and has forlts ObJGCt to provide a simple method of fixing the rails upon the sleepers both for the normal gauge of track and also for the increased gauges correspondingto bends in the track. The improved method of fixing is also required to safely transmit through ample surfaces all forces acting between rails and sleepers in the different directions, particularly the transverse forces acting horizontally in the longitudinal direction of the sleeper which occur between rails and sleepers, in contradistinction to the known rail fixing devices with which the transmission of the transverse forces takes place at the edges of the holes in the sleeper covers.

These known rail fixing devices have the disadvantage that on account of the smallness of the contact surface between the edges of the holes, on the one hand, and the bolt shank or the hook of the hook plate, on the other hand, rapid wear takes place which is still further increased by the circumstance that with the putting together of the track a certainamount of play must be present between edges of the holes and bolt shanks or hooks. which play from the beginning prevents a satisfactory contact 0 the surfaces and therewith leads to the loosening and rapid wearing out of the parts. A further disadvantage of the known arrangement is that, corresponding to the gauge of the track j'at curves, the holes which serve for securing the two rails must have a correspondingly greater distance from one another, and that consequently a greater number of different sleepers must be prepared and held in stock. The invention consists herein, that the sleepers are provided with teeth arranged side by side in the longitudinal direction of the sleepers, and that the parts serving for fixing the rails upon the sleepers at their 1'; points of contact with the sleepers are like wise provided ,with teeth which can be brought selectively into engagement with the teeth. of the trans verse sleepers corresponding to the desired gauge of track. Preferably '3: the'teeth of the'transverse sleepers are arranged upon surfaces sloping downwardly from the outer edges of the transverse sleepers and inwardly directed.

According to the invention the parts serving for fixing are adapted to transmit to the said sloping surfaces both the horizontal counter-forces corresponding to the pressure of the rails upon the surfaces of the sleepers and also the horizontal forces occurring in the direction of the rails between rails and sleepers, while the horizontal forces occurring (in the longitudinal direction of a sleeper) between rails and sleeper are taken up by he teeth of the sleepers.

The invention is illustrated in four constructional examples in the accompanying drawings.

Referring to' Figures 1 7, a is a rail of the t-raclg'baniron transverse sleeper which in the constructional example illustrated has a T-shaped cross-section. The sleeper Z) provided on both sides with sloping surfaces 25 which slope downwardly froin the outeredges of the sleeper and are inn-ardly directed. On one of the two sloping surfaces (that shown on the left in Fig. 2) teeth I)? are arranged parallel, these teeth being provided at the plane at which (for the-occurring gauges of track) the rails are fixed uponthe sleep ers. The teeth Z2 are preferably formed by being rolled-in into the sloping surfaces.

. They may also be .rolled-in over the entire engages over lov means of three bolts 6, f, and g.

and likewise is provided with teeth length of the sleeper into the one sloping surface (or into both sloping surfaces). cis a supporting plate the length of which in the direction of the rails is greater than the width of the sleeper, and the breadth of which in the direction of the sleeper is greater than the breadth of the rail-foot. The plate 0 lies flanges 0 and c projecting downwardly over the edges of the sleeper. The flange 0 can he pushed with. its corresponding sloping susface into engagement with the surface I). The flange 0 carries a surface sloping down-- wardly and outwardly directed, which, when the flange 7 the one sloping surface 5, is reinored a short distance from the other sloping surface 6 supporting plate 0 has, further, upward projecting flanges c and c "Allie flange 0* the rall foot, the flange 0 carries at a distance from the rail foot a surface 0, sloping upwardsand outwardly directed. The fixing of the sleeper to the rail is effected bolts 6 and f which are similar to one another have heads 6 orf of trapezium-form in crossparts 79 of the sleeper.

c is pushed into engagementwnlr lhe i which are directed downwardly sloping from the outer section, of which the sloping side surfaces are provioed with teeth 6 or 7?. cl, (Z are wedgeshaped supp rting plates which are'pushed over the bolts 6 and y, and abut with the one wedging surface on the rail foot and the other wedging surface on the sloping surface 6". On tightening the nuts 6 f 9 the supporting. plate 0 is pushed withthe flange a solid against the one sloping surface I) of the sleeper Z), the rail 64 is pressed with its rail foot solid upon the flange 0 of the supporting plate engaging thereover, and the rail a is pressed solid upon the supporting plate 0, which again is pressed solid upon the sleeper 7). i i

' Referring to Figs. 81-2 (1 is a rail ofthe track, Z) an iron transverse sleeper which is of the hollow kind in the constructional example illustrated. The sleeper b is provided on its upper surface with laterally projecting flanges wiich have toothed surfaces b sloping downwards from their outer edges and inwardly directed: Upon the edges of the sleeper Z) two bow-shaped supporting plates h are laid under the rail foot, each of which has a toothed flange h extending laterally over the edge of the sleeper and projecting'downwards and engaging in one of the two toothed Further each bowshaped supporting plate 72. has onboth sides of therail upwardly projecting hook-shaped 1 flanges h and k The flange'h abuts upon the rail foot and has a passage opening h for a screwbolt. at a distance from the rail foot with a plain inwardly sloping and downwardlyv directed surface. Between. this surface and the rail foot a wedge 70 provided with a boring can be pushed. Through the passage openings h of the two bows h ascrew bolt a is-passed and through the-borings of the two wedges'k a screw bolt m is passed which can be tightened up by means of nuts a and m. ing the nuts 71/ and m the two supporting plates h are simultaneously pressed with their toothedllanges it against the toothed oft-he sleeperb,thera1l a sloping surfaces 5 is-presseld against the llangelh of the supporting plate 7t and the rail is also pressed vertically downwards upon the supporting plate an l t is latter upon the sleeper.

lleferrrngto Figs. 13-20, the rail a 1s ltld' immediately upo'n'the sleeper b which in the constructional example illustrated has a T shaped cross-section. The sleeper b is providedon both sides with sloping surfaces b and inwardly At the places at which (for the occurring gauges of track) the rails'are-fixed upon the sleepers, teeth b located parallel are arranged upon the sloping'surfaces Z). '11, tare two bows laid under the rail footon both sides new the'sleeper, which bows have a lateral toothed resent engaging in the teeth b of Theiother flange h is provided 1 By tighten-i edges of the sleeper;

the abutting surface Z). Each of the two iron bows i has two upwardly projecting hookshaped flanges and 2 The hook-shaped flange engages over the rail foot. The hook-shaped flange 2' carries at a short distance from the rail foot a surface i inwardly sloping and downwardly directed. Between this surface and the rail foot a wedge is provided with a boring can be pushed. Through the hooks 71 of the two bows 2' a screw bolt 91 is passed and through the borings of the two edges 7: ascrew bolt 11?. is passed, which bolts can be tightened by means of nuts n and 727/. By tightening the nuts 'n/ and m the rail a is pressed against the sleeper b and simultaneously the iron bows 2' are pressed with their toothed portions 2" against the toothed sloping surfaces 6'' of the sleeper b and the foot of the rail a is pressed against the hook-shaped flange 2 of the how i.

The top carrier flange of the T-shaped sleeper may, as seen in Fig. 15, have the I curved form in the nonstressed condition, and

only be stressed into the flat form shown in Fig. 14 by tightening the nuts n and m. The tension thus produced conduces to maintaining the tension in all the connections.

Referring to Figs. 21-26, in the constructional example shown herein the rail a is fixed upon a supporting plate p and this is fixed upon two sleepers 6, 7) arranged in pairs at a short distance from one another. The two sleepers b, b are provided on their outer edges with sloping surfaces 5, b which are directed sloping downwards and inwardly, and at the places where the rails are fixed upon the sleepers (for a given gauge of track) are provided with teeth b arranged parallel in the longitudinal direction of the sleepers. At their inner edges both sleepers b, a are provided with surfaces 6 b sloping downwards and outwardly directed. p is a supporting plate the length of which in the direction of the rails is greater than the total breadth of both sleepers. The toothed portions of the flanges p projecting downwardly over the sleeper edges engage in the toothed portions 7f, 71 of the two sleepers. The supporting plate 7) has also on one side near its end two upwardly directed flanges p 72 with which it embraces the rail foot and on the other side in the middle portion a widening p which is provided with a plain flange 72 sloping upwards and outwardly The rail is pushed upon the supporting plate 19 against the flanges 29 Then a wedge piece 0 is inserted which abuts with its one sloping surface against the rail footand with its other sloping surface against the flange 79*. Below this wedge piece an intermediate member 8 formed wedge-shaped inwardly and outwardly is laid with its outer sloping surfaces against the sloping surfaces 5 b of the sleepers. Then a bolt 7 is pushed through corresponding borings of the intermediate member s and the wedge piece 0 and by means of the nut 1" the wedge-shaped head 1' is pressed against the intermediate member 8.

By tightening up the nut r the two sleepers are pressed away from one another at their upper parts and their inclined toothed portions are pressed into the toothed portions of the flanges 2;; further the rail foot is pressed solid against the flanges 29 the rail is pressed solid upon the supporting plate 7), and the latter is pressed solid upon the two sleepers b.

The top carrier flanges of the two sleepers may, as seen in Fig. 23, have the curved form in the non-stressed condition and only be stressed into the flat form shown in Fig. 22 by tightening the nut r.

The constructional forms shown in Figs. 1-7, Figs. 8-12, Figs. 13-20, are also adapted for use with the transverse sleepers bedded into a concrete foundation.

Also with all constructional forms rails with the usual cross-sectional form may be used instead of rails of the kind having a sloping away foot.
